Synthesis of BaMgAl10O17:Eu2+ phosphor by Solution Combustion Method |
| 초록 |
The BaMgAl10O17:Eu2+ phosphor has been applied to fluorescent lamps and plasma display as an efficient blue component. Commonly, BaMgAl10O17:Eu2+ has been prepared by conventional solid state method at high temperature. In this experimental, the BaMgAl10O17:Eu2+ blue phosphor has been successfully prepared by a solution combustion method. The stoichiometric amount of metal nitrates were dissolved in a minimum quantity of deionized water, then the weighed quantity of urea was added and stirred well to obtain homogeneous solution. The solution filled in porcelain crucible was introduced into a muffle furnace pre-heated to 600oC. The solution in the crucible was dried very quickly and then ignited with spouting out flames. The phosphor powders obtained were characterized by using X-ray diffractometer, SEM and VUV-PL measurement system. The BaMgAl10O17:Eu2+ particles are shaped to plate-like type. The brightness is compared to that of commercially-available blue phosphor. |
